Definitions
- EP-A-0 171 069 In order to reduce this expenditure of time, it is proposed in EP-A-0 171 069 to first lower the solidified layer more than necessary and then to raise it again to the final dimension. But this can solve the problem of inaccurate Do not loosen the layer thickness.
- EP-A- proposes to wipe off excess plastic material with a scraper and to set the layer thickness precisely. It has been shown, however, that the known scraper tends to increase local disturbances, particularly in the case of thin layers with a layer thickness of 0.1 mm or less.
- a device 8 for solidifying the uppermost layer 7d adjoining the surface contains an illuminating device 9 with a light source which generates a bundled light beam 11 via an optical system 10.
- a deflection mirror 12 is arranged approximately in the middle above the container 1, which is gimbally suspended and can be pivoted by a schematically indicated pivoting device 13 such that the light beam 11 directed at the mirror 12 from the mirror 12 as a reflected light beam 14 to essentially everyone Place of the surface 2 can be positioned.
- two rotating mirrors, one for each coordinate direction, can be used in a known manner.
- a computer 24 is provided with the lighting device 9, with the swivel device 13, with the height adjustment device 6 and with the displacement device 16 for carrying out the following coupled steps described.
- This thickness setting is preferably carried out by selecting the displacement speed of the scraper 16, but also depends on the viscosity of the plastic 3 , the elasticity of the element 20 and the distance between the surface 25 of the previously solidified layer and the lower edge 21 of the stripper 15. If these parameters are set correctly, a flat film of liquid material 3 is formed directly behind the stripper 15. For this purpose, a corresponding relation can be stored in the computer 24 in the form of a table or equation, which is determined empirically.
- the lighting device 9 and the swiveling device 13 are controlled by the computer 24 in such a way that the reflected light beam 14 strikes the locations of the liquid plastic layer corresponding to the shape data created and processed in the computer 24, and solidifies there in a known manner through polymerisation tion causes.
- the displacement of the scraper 15 and the control of the light beam 14 can take place at the same time in such a way that the light beam tracks the scraper 15 and strikes the plastic layer in the area immediately behind the scraper (viewed in the direction of its movement). so that the hardening or hardening of the plastic layer takes place immediately after the setting of the layer thickness.
- the height adjustment device 6 is lowered by the computer by the amount of the intended thickness of the next layer 7b.
- liquid plastic flows from the sides over the solidified areas of the first layer 7a, so that initially no uniform layer thickness is established.
- the stripper 15 is in turn moved over the surface 2 and, due to its coating effect, in turn produces a liquid layer of a constant thickness which is preselected as a function of the above-mentioned parameters.
- the scraper 15 causes the surface to be slightly lowered in the area of the liquid volume and not, as is the case with rigid scrapers protrudes from the surface at the edge.
- the solidification takes place in the same way as for the first layer 7a.
- the further layers are then produced analogously.
- a particularly advantageous application of the scraper according to the invention is in the method according to claim 10.
- the solidification of a layer or the connection with the underlying layer does not take place uniformly over the entire extent of the layer, but only at defined first areas, so that between these solidified first areas In each case, second areas with liquid material 3 remain, which are solidified in a subsequent work step. This reduces the deformation of the object due to the shrinkage of the material when it solidifies. However, this process leads to an irregular surface.
